True or False. All segments have a perpendicular bisector.

<span>Without drawing a line on a piece of graph paper. If you know the endpoints of the line segment you can determine the equation of the line and the midpoint of the line. The slope of a perpendicular to a line is the negative reciprocal of the slope of the original line. You can then determine the equation of the perpendicular bisector using the point-slope method. Using a compass and straight edge, you can draw the line. set the compass at the endpoint and wide enough to extend beyond the midpoint. Scribe an arc. Without changing the compass use the other end and scribe another arc so that the two arcs intersect. Connect the two points where the arcs intersect and scribe a line through them. That is the perpendicular bisector.

Which is the graph of f(x) = 5(2)x?

gayaneshka [121]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$f(x)=5(2)^{x}$

This is a exponential function of the form

$f(x)=a(b)^{x}$

where

a is the initial value

b is the base

In this problem

a=5

b=2

using a graphing tool

see the attached figure

One angle of a triangle has a measure of 66. The measure of the third angle is 57 more than half the measure of the second angle

Daniel [21]

So let's say that the second angle is x.

Then we can say that the third angle is $\frac{1}{2}x+57$ .

So then we have three angles:

1) 66°

2) x°

3) ( $\frac{1}{2}x+57$ )°

So then we can add these together and solve for x by setting it equal to the total degrees left in the triangle after subtracting the known angle:

$x+\frac{1}{2}x+57=114$

$\frac{3}{2}x+57=114$

$\frac{3}{2}x=57$

$\frac{2}{3}*\frac{3}{2}x=57*\frac{2}{3}$

$x=\frac{114}{3} =38$

So now we know that the measure of the second angle is 38°. So then we can use this value to solve for the third angle:

$\frac{1}{2}(38) +57=76$

So the values of the angles are:

1) 66°

2) 38°

3) 76°

If the areas of two similar hexagons are to each other as 5 : 2, and one side of the first hexagon is 25, what is the correspond

Inessa05 [86]

5:2 = 25:x

25 = 5 * 5
so
x = 2 * 5 = 10

Why cant bicycles stand up by themselves

Snezhnost [94]

They can, its just very difficult to get them to because their tires aren't solid and flat so the bike can tip easily. their centre of gravity also moves easily so it is very difficult to balance them.

hope this helps :)
